3.2.4.1.1 Scanning a Path for a Previous Version Token
The application requests a previous version of a file by placing a time indicator in the path as a directory element, as specified in section 2.2.1.1.1. For any path-based operation (for example,SMB_COM_NT_CREATE_ANDX) the client SHOULD scan the file path being provided by the application for a formatted @GMT token.
If a previous version token is present in the pathname as a directory element or a final target, the client SHOULD<79> set the SMB_FLAGS2_REPARSE_PATH flag in the SMB header of the request.
